Description compwiz 2000-10-07 16:56:11 EDT
Generally when ifup uses an interface which uses DHCP and which updates
DNS, /etc/resolv.conf gets updated. /sbin/pump has an option -d which makes
sure /etc/resolv.conf isn't updated every time. This should be an option in
ifcfg-* so I don't have to edit ifup manually.
Comment 1 Nalin Dahyabhai 2000-10-10 14:10:08 EDT
This can also be controlled by editing your /etc/pump.conf file, but it might be
a good idea to add that as an option in the init script (by overloading
PEERDNS?) since I'm not sure how you do this in dhcpcd's configuration files.
Comment 2 compwiz 2000-10-10 15:20:39 EDT
Well, -R is the dhcpcd equivalent to -d in pump. And /etc/pump.conf isn't
created by default, so it wouldn't really be obvious.. it would make a lot more
sense to put it in a variable in ifcfg.. Basically this is what my lines 94 & 95
look like in /etc/sysconfig/network-scripts/ifup:

PUMPARGS="-d -h ${DHCP_HOSTNAME}"
DHCPCDARGS="-R -h ${DHCP_HOSTNAME}"
(As opposed to without -d & -R)
Comment 3 Bill Nottingham 2000-12-12 03:06:07 EST
Sounds like a plan. Added in initscripts-5.53-1; just add
PEERDNS=no
to /etc/sysconfig/network-scripts/ifcfg-eth*.
